      <p>
       [non-functional] constraints describe quantitative and non-functional aspects of the actors and users behaviour and missions, such as latency requirements, safety issues, security constraints, need variability, and more.
      </p>
      <p>
      </p>
      <p>
       They can be applied to any element of the need description, such as activities, interactions, operational processes, data...
      </p>
      <p>
       A same consttraint can be applied to several elements.
      </p>
      <p>
      </p>
      <p>
       Later in the process, each architecture definition decision will be confronted to each of these constraints, so as to ensure compliance of the system architecture with regards to need.
